求教原子哥,fatf的文件目录的遍历

ele-madman

             各位牛人,菜鸟我最近在弄fatfs的文件遍历遇到一个问题.....f_readdir这个函数    读  长文件名没有问题,,,,,但读短文件名时  其中几个字符顺序颠倒,或者稍长一点的8.3格式的就只读前面两三个字符

FRESULT scan_files (char* path)
{  
    FRESULT res;
    FILINFO fno;
    DIR dir;
    int i;
    char *fn,*p;
    FATFS fs;
    static char lfn[_MAX_LFN + 1];//(_DF1S ? 2 : 1)
    fno.lfname = lfn;
    fno.lfsize = sizeof(lfn);

 
 f_mount(0, &fs);
    res = f_opendir(&dir, path);
    if (res == FR_OK) {
        i = strlen(path);
        for (;;) {
            res = f_readdir(&dir, &fno);
            if (res != FR_OK || fno.fname[0] == 0) break;
            if (fno.fname[0] == '.') continue;
#if _USE_LFN
            fn = *fno.lfname ? fno.lfname : fno.fname;
#else
            fn = fno.fname;
#endif
            if (fno.fattrib & AM_DIR) {
                //sprintf(&path, "/%s", fn);
               // res = scan_files(path);
                //if (res != FR_OK) break;
                //path = 0;
            } else {
                //printf("%s/%s\n", path, fn);
        //if(fn=="789456")p++;
            }
      //fno.fname={"0000000000"};
        }
    
    }
     f_mount(0, NULL);             
    return res;
}

比如读"123.txt"就读出了"123txt.T",       "123456.txt"读出“123”  。。。。。。

 

正点原子

回复【楼主位】ele-madman:
---------------------------------
这是你代码问题了,遍历的代码,我们战舰板的fatfs例程,就有提供,还是通过usmart控制的,很好测试.你可以看看我们fatfs例程,战舰板的.
